to which it pertains to make and use the same.

My invention relates to improvements in oil-stoves.

The object of my invention is, first, to provlde a combined doublechimney that may easily be removed from the stove for convenience incleaning, and that may be tilted for lighting the wicks by operating alever that extends outside of the stove.

A further object is to provide a grate or vessel-support that,when inposition, is firmly locked by a cam-lever, and that may be easilyremoved from the stove.

With these ends in view my invention consists in the parts andcombinations of parts, as will be more fully described, and pointed outin the claims.

In the accompanying drawings, Figure 1 is a view in perspective of adouble stove. stove on the left hand. is in position for use while theone on the right hand is tilted back, showing the wick-tubes, air-plate,&c., and on the tilted part the cones that support the chimneys. Fig. 2is a View in perspective, showing the manner of tilting the chimneys forlighting the wicks, but with the grate removed. Fig. 3 is a view inperspective of the top grate or vessel support and attachments. Fig. 4is a vertical section of the locking device connected with the grateshown in Fig. 3. Fig. 5 is a view in perspective, showing the upper andlower parts of the lever shown in Fig. 4. Fig. 6 is a view inperspective of the double chimney and the device for tilting the same.Fig. 7 is aview in perspective of a portion of the oil-container. Fig. 8is a vertical section of the stove from side to side, and Fig. 9 is asectional View showing the inside formation of the lug on the lockingdevice.

A represents the base or supporting frame, inside of which is securedthe oil-container A, and upon which are mounted the stoves or drums B,secured to the part A by the legs I). The lower part of the drum B, towhich The are directly attached the said legs, is abroad I Below theplate B, and attached to the.

of the stove and provided with the thumbwheels D, and are for raising orlowering the wicks inthe usual manner. I

In stoves of this class it isimportant that as little heat as possiblebe transmitted from the parts above to the oil-container below. Tothisend the hinges at the rear, (not shown,) consisting of lugsextending respectively from the parts B and B, and pivoted on a commonrod in the usual manner, are fitted loosely to each other and to therod, so that but little heat will pass between the parts at this point.

The legs I) are provided, respectively,with the ribs 1), and the part Bwith the teats If, that engage each other when the parts are inposition, and by means of which the part B is slightly separated fromand has no contact with the parts below, except, as aforesaid, at theteats and hinges. The bodies E of the chimneys are made, preferably, oftin or some bright metal, and providedin front with openings coveredwith isinglass E, through which the flames may be seen from the outsideof the chimneys.

The chimneys E are provided respectively on their upper and lower edgeswith the metallic frames 6 e, which latter, with the chimneys E, aresecured together by the vertical screw-bolt e. The bottom plate of thedrum B has slots or openings for the passage of wick-tubes, are the rodsD,extending in front the wicks upward, and the portions of the platenext these slotsare raised, forming whatis known as cones. (Shown at Lin Figs. 1 and 2.) These plates with the said slots and cones are madein the usual manner, and no claim is made on this part of the ICCdevice. The chimneys fit nicely around these cones, preventing anylateral displacement of the chimney. The chimneys are cut away, as

shownat 6', so that when they are tilted back,

is provided on the inner end with a hole or socket that embraces the lugf, attached to the frame e. By pressing on the outer end of the lever orthumb-piece the chimneys are tilted back, so that the wicks may belighted, as shown in Fig. 2.

From the foregoing it will be seen that the construction and arrangementof the chimneys is such that they are solidly held in position and aresafe and easy to operate. A door, B, in the front part of the drum givesaccess to this part of the drum, and as the said door is provided with awindow of isinglass the flame may be seen from the front of the stove.

G is the grate or skeleton frame secured to the top of the device, andupon which vessels or other articles that are to be heated are placed.The grate is provided on top with small lugs 9, that slightly elevatearticles with flat bottoms from the face of the grate. On

opposite sides of the grate are legs that rest upon the top of the drum,while midway be tween these legs on either side the grate are the ears Hand H, that extend upward from the drum. These earshaveinwardprojections that extend toward each other and are adapted to project orrest under the outer rings or edge of the grate where the grate isprovided with the webs I and I, that are depressed below the other partsof the grate, so that when the rim of the grate rests on top of the saidears the said webs pass under the said inward projection of these cars.The web I has a small boss, 1', that engages the concaved under side ofthe projecting part of the ear H. The inwardly-projecting arm of the earH has a pendent rib, h, that engages the transverse groove j in thecam-lever J. (Shown also in Fig. 5.) web I is provided with the ribs t",between which the end of the cam-lever is inserted, and when the leveris pressed down in the position shown in Fig. at the grate is lockedfirmly in its place. It will be observed that as the cam'lever draws theadjacent part of the rim of the grate down onto the ear H the legs 9'act as fulcrums, so that the opposite side of tion, in the presence oftwo witnesses.

grate is raised, pressing the boss 0' firmly into its seat under the armof the ear H. No screwdriver, wrench, or other tool is required toattach or detach the grate, and either operation requires but a momentof time.

The oil-pan is provided preferably at a The point between the drums withthe orifice 0, through which oil is poured into the container. Thisorifice is encircled with a rib, P, extending upward and located somedistance outside the orifice and inside of vthe rib. The surface of saidpan slopes toward the orifice from all directions, forming an apron tocatch the drip from the oil-can that usually accompanies the filling ofthe container with oil.

R (see Fig. 1) is a cover for the filling-orifice. This cover (which isalso a name-plate on which the name of the consignee can be molded orengraved) is made detachable, so that after the stoves are manufacturedand stored ready for shipment, these covers may be prepared in suchnumbers as are required for each consignment of stoves, and marked withthe consignees name, or such other letters, figures, or characters asthe local trade may require at the places wherein the goods are to beput upon the market. 0 is surrounded inside of the container with a wallof perforated metal plate or gauze, S. This wall or partition branchesoff in different directions through the container, and when the stove ismoved breaks the momentum of the fluid and prevents it from sloppingthrough the orifice 0; also, the plates S around the orifice act asstrainers.

What I claim is I 1. In an oil-stove, the combination, wit the basethereof and a drum hinged thereto, and provided with a door, of chimneysloeated in and resting on the bottom of said drum and a'lever connectedto the upper portion of said chimneyand passing through the front of thedrum, whereby the chimneys may be tilted simultaneously independently ofthe drum, substantially as set forth.

2. The combination, with the drum having laterally-extending ears, of agrate having webs or arms registering with and adapted to extend underthe laterally-projecting ears of the drum, and a cam-lever engaging oneof said ears and the adjacent web or arm on one side of said grate forlocking the parts together.

3. The ears H and H, constructed, as aforesaid, in combination with thegrate G, provided with the parts I and I, the former provided. with thelug 1', adapted to engage a seat on the ear H, and the latter providedwith the ribs 1', forming aseat between them for the cam-lever, and thelegs 9, operating as fulcrums, so that as the cam-lever presses one sideof the grate firmly upon the ear H the parts I and i will be raisedtoengage the said seat on the ear H, substantially as set forth.

In testimony whereof I sign this specifica- HU'GH MCCONN ELL.
